I'm somewhat interested in doing editing work for these. I'm not sure if you guys are looking for a volunteer editor, and we'd have to negotiate before I would want to commit to such a huge project, but I'm inquiring about this.

I have three years of experience as a writer's group organizer, have been paid to edit two books in the past, and I write practically constantly (though I have not attempted to get published).

P.S. I have an editing suggestion, myself: there are places that use odd wording that is reminiscent of ancient holy books. This might contribute to The Singularity Institute's Arrogance Problem as well as making lesswrong.com look like a phyg.

Update: I have SEO training. I forgot to mention that. This isn't as useful for an e-book as for web pages but I don't see why you'd have someone edit only the e-book and not the web pages only to end up with two different versions.
